On Thursday night, celebrities and artists stopped at Tryst Nightclub following the grand opening of Wynn Las Vegas’ new Japanese restaurant Mizumi.

The nightclub kicked off its first night of Wynn Music Week with Thomas Gold in the DJ booth situated in front of the 90-foot cascading waterfall. Pop princess Ashley Tisdale joined the partygoers followed by blonde bombshell Paris Hilton. Cheryl Burke of “Dancing with the Stars” arrived at the crimson venue and joined the stars at a private table next to the dance floor.

As the evening continued, world renowned DJ talent flooded the venue. One-third of electronic dance music trio Swedish House Mafia Sebastian Ingrosso graced the venue joined by resident DJ Alesso.

The two made a surprise appearance on stage as confetti fell from the ceiling and the crowd erupted, waving Tryst glow sticks in the air. The music continued to pump as fans and celebrities danced into the early hours of the morning.
